Indian Prime Minister Manmohan Singh (R) waves to the media as Bangladeshi counterpart Sheikh Hasina watches upon his arrival at the Hazrat Shahjalal International Airport in Dhaka September 6, 2011. Singh arrived in Bangladesh on Tuesday for a visit aimed at mending often fractious ties but breakthroughs on main disputes, including the sharing of water from rivers, look unlikely.
